This disclosure, its aspects and implementations, are not limited to thespecific components, assembly procedures or method elements disclosedherein. Many additional components, assembly procedures and/or methodelements known in the art consistent with the intended fin frameassemblies will become apparent for use with particular implementationsfrom this disclosure. Accordingly, for example, although particularimplementations are disclosed, such implementations and implementingcomponents may comprise any shape, size, style, type, model, version,measurement, concentration, material, quantity, method element, step,and/or the like as is known in the art for such fin frame assemblies,and implementing components and methods, consistent with the intendedoperation and methods.

Referring to FIG. 1, an underside view of an implementation of a singleside direct cooling (SSDC) unit is illustrated. The SSDC unit 2 includesa cooling jacket 4 coupled to an SSDC package 8, as illustrated. Invarious implementations, the cooling jacket 4 may be configured tocouple to a baseplate 6 over a fin frame 10, as illustrated. In variousimplementations, heat is produced by the SSDC package 8 and istransferred to the baseplate 6, which is in close physical contact withthe SSDC package 8. In such implementations, the baseplate 6 is made ofa thermally conductive material, such as, by non-limiting example, ametal, a ceramic, a metal alloy, a combination of metal and ceramic, acomposite, or any other thermally conductive material shapeable into aplane and/or pin form. By non-limiting example, the fin frame 10includes pins, fins, or projections that extend away from the baseplate6 to increase the surface area, thereby improve thermal conductivity. Invarious implementations the baseplate 6 and the fin frame 10 may form afin frame assembly or conductive plate.

Referring to FIG. 2, a top side view of the implementation of the SSDCunit of FIG. 1 is illustrated. In this alternative view, the SSDC unit2, which includes the cooling jacket 4 coupled to the SSDC package 8, isillustrated. As illustrated, the cooling jacket 4 may be configured tocouple to the baseplate 6 over the fin frame 10, placing the pluralityof pins of the fin frame 10 into an opening in the baseplate 6.

Referring to FIG. 3, a cross-sectional view of the implementation of theSSDC unit 2 of FIG. 1 is illustrated. The SSDC unit 2 includes thebaseplate 6, as illustrated. The baseplate 6 may be coupled directly to,or coupled through one or more layers of material to, a substrate 16, asillustrated. In various implementations, the substrate may be a directbonded copper (DBC) substrate, a gallium substrate, a silicon substrate,an aluminum nitride substrate or any other substrate material, bynon-limiting example. As illustrated, a plurality of semiconductor die14 may be coupled to the substrate 16. As illustrated, the SSDC unit 2includes the cooling jacket 4 coupled to the baseplate 6 over the finframe 10. The SSDC unit 2 includes a fluid passage 12 configured to passa fluid into and through the cooling jacket 4 to an exit fluid passage.In various implementations, the cooling jacket 4 directs a cooling fluidto pass over the plurality of pins/fins/projections of the fin frame 10during operation of the semiconductor devices coupled to the substrate,thereby removing heat generated by the semiconductor devices. In variousimplementations, by non-limiting example, the cooling fluid may bewater, air, or any other compound or mixture that may increase theamount of heat that can be dissipated away from the SSDC package 8.

Referring to FIG. 4, an implementation of a pin fin assembly including abaseplate is illustrated. A plurality of pins 11 are coupled to abaseplate 7, as illustrated. In various implementations, this baseplate7 is constructed of a flat, substantially planar, solid piece ofthermally conductive material, such as, by non-limiting example,aluminum, copper, nickel or other metallic materials. In variousimplementations, the baseplate 7 is configured to couple to a substrate,and to be included in an SSDC package as previously disclosed. Invarious implementations, the plurality of pins 11 may altogether form afin frame, or fin frame assembly, to be included in an SSDC package aspreviously disclosed. As illustrated, the plurality of pins 11 arecylindrical in shape, though they may be of any other shape, such as, bynon-limiting example, rectangular, triangular, trapezoidal, or anotherthree dimensional shape.

Referring to FIG. 5, an implementation of a fin frame assembly includinga baseplate is illustrated. The fin frame assembly includes a baseplate18, as illustrated. In various implementations, the baseplate 18 isdesigned couple to a substrate like any type disclosed in this document.As illustrated, the fin frame assembly also includes a fin frame 20. Thefin frame 20 includes base portion 22, which is coupled to the baseplate18, as illustrated. In various implementations, the base portion 22 ofthe fin frame 20 is substantially planar, and is configured to coupledirectly to the baseplate 18, though the fin frame 20 can be configuredto couple to a baseplate with a non-planar or textured surface as well.Each of a plurality of fins 24 extends and protrudes from the baseportion 22, as illustrated. Additionally, the fin frame 20 includes eachof a plurality of openings 26 through the fin frame 20. In variousimplementations, during manufacture of the fin frame 20, each fin 24 maybe partially “punched” out from the base portion 22, and bent upward, soas to protrude away from the base portion 22. In this way, the shape ofeach of the plurality of openings 26 corresponds with the shape of eachfin 24 as each fin 24 originally resided in the opening 26 before beingbent upward.

In various implementations, an outline of the plurality of fins 24 maybe cut from a single sheet of material, and the fins 24 may be bentupward, as previously disclosed. In various other implementations, theplurality of fins 24 may be formed from a single sheet of material thatis pressed into a die, thus puncturing the sheet of material and formingeach of the plurality of fins 24 and the plurality of openings 26simultaneously. In various implementations, the fin frame 20 is made ofa homogeneous material, with the base portion 22 and the plurality offins 24 being constructed of the same material. In variousimplementations, the fin frame 20 may be formed of a single piece ofmaterial; in other implementations, the fin frame 20 may be formed oftwo or more layers of material coupled together. In still otherimplementations, the plurality of fins 24 may be treated to furtherenhance their thermal conductivity, such as by, non-limiting example,coating, plating, etching, or otherwise depositing, removing, orexchanging material from the fins. This processing of the fins 24 may bedone along with or separately from the remainder of the fin frame 20.

Referring to FIG. 6, the fin frame assembly and the baseplate of FIG. 5shown separately are illustrated. As shown, the fin frame 20 includes abase portion 22 and a plurality of fins 24 that are formed of one pieceof material. In various implementations, by non-limiting example, theplurality of fins 24 are formed separate from the base portion 22 andmay be bonded to the base portion 22 by various methods and processes,including, by non-limiting example, welding, gluing, epoxy, soldering,bonding, or any other method of coupling two materials together. Inimplementations where the fin frame 20 is formed of one piece ofmaterial, each fin of the plurality of fins 24, may be bent upward from,punched out from, stamped, pressed, etched, or otherwise formed from,the base portion 22, so that the fins 24 are a plurality of foldedprojections that extend away from, or protrude from, the base portion22, creating a plurality of correspondingly shaped openings 26 in thebase portion. In such implementations, a shape of each opening of theplurality of openings 26 corresponds substantially with a shape of eachfin of the plurality of fins 24. As illustrated, the shapes of each fin24 and each opening 26 may be rectangular. In other implementations, bynon-limiting example, the shapes of each fin 24 and each opening 26 maybe triangular, square, trapezoidal, or may be of any other shape. Invarious implementations, once the fin frame 20 is formed, it may bebonded or coupled to the baseplate 18 by welding, epoxy, glue,soldering, or any suitable combination thereof, by non-limiting example.The fin frame assembly can then be used with a SSDC by any meansdisclosed herein.

Referring to FIG. 7, a top view of the baseplate of FIG. 6 isillustrated. The baseplate 18 may include holes/openings 28 whereby thebaseplate 18 may be attached with screws, pins, or any other attachingmeans, to an SSDC, the cooling jacket, substrate, or another component.As illustrated, the baseplate 18 may be substantially rectangular,square, circular, or of any other suitable shape according to thedisclosure herein.

Referring to FIG. 8, a top view of the fin frame assembly of FIG. 6 isillustrated. The fin frame 20 includes the plurality of fins 24, orprojections, that are bent upward, and protrude away from the baseportion 22 of the fin frame 20, as illustrated. In variousimplementations, by non-limiting example, each fin 24 may extend orprotrude at an about 90 degree angle relative to the base portion 22, oreach fin 24 may extend or protrude at any other angle greater than 90degrees or less than 90 degrees relative to the base portion 22, so asto allow the flow of a fluid, such as, by non-limiting example, water,air, gas, or any other flowable fluid over the fins 24. In other variousimplementations, by non-limiting example, each fin 24 may extend orprotrude at differing angles relative to each of the other fins 24 andto the base portion 22. As illustrated, voids created by the folded andprotruding fins 24 creates openings 26 that correspond with the shape ofeach fin 24. In various implementations, the shapes of each fin of theplurality of fins 24 may be the same, or they may be different relativeto each other. As illustrated in the version in FIG. 9, the fins 24 areuniform in size and shape, and are arranged in staggered alternatingrows across the base portion 22. This arrangement may be formed toimprove the thermal conductivity of the fin frame 20 and fins 24. Inother various implementations, by non-limiting example, the fins 24 maybe arranged in any other pattern on the base portion 22.

Referring to FIG. 9, a magnified view of the fin frame assembly of FIG.6 is illustrated. As shown, the fin frame 20 includes the base portion22 and the plurality of fins 24 formed of one single piece of material.As illustrated, each fin or projection of the plurality of fins 24protrudes away from the base portion 22 at an edge of each correspondingopening 26 within the base portion 22 of the fin frame 20. In variousimplementations, by non-limiting example, the plurality of fins 24 maybe formed to extend to the edge of the fin frame 20, with the opening 26creating a notch/re-entrant opening in the edge of the fin frame 20, asillustrated. However, in other various implementations, the fins 24 maynot fully extend to the edge of the fin frame 20. In variousimplementations, each fin of the plurality of fins 24 may be longer inlength than in width, and may have rounded corners, to form asubstantially rectangular shape, as illustrated. Though in other variousimplementations, by non-limiting example, the fins 24 may be a widevariety of other closed shapes, sizes, and different orientations.

Referring to FIG. 10, a lengthwise side view of the implementation ofthe fin frame assembly of FIG. 5 is illustrated. The base portion 22 ofthe fin frame is coupled with the baseplate 18, as illustrated. Theplurality of fins 24 extend, protrude, or project outwards from thebaseplate 18 and base portion 22, as illustrated. Referring now to FIG.11, a widthwise side view of the implementation of the fin frameassembly of FIG. 5 is illustrated. This widthwise side view shows thatin the direction of flow the pins do not obstruct flow as much as theydo in the lengthwise view, allowing the fluid to flow around the variouspins without much pressure drop across the fin frame.

Referring to FIG. 12, another implementation of a fin frame assemblyincluding a baseplate is illustrated. The fin frame assembly includes abaseplate 32, as illustrated. In various implementations, the baseplate32 is designed to couple to a substrate like any disclosed herein. Asillustrated, the fin frame assembly also includes a fin frame 34. Thefin frame 34 includes a base portion 36, which is coupled to thebaseplate 32 using any structure or system like those disclosed herein.In various implementations, the base portion 36 of the fin frame 34 issubstantially planar, and is configured to couple to the baseplate 32,though the fin frame 34 can be configured to couple to a baseplate witha non-planar surface as well. Each of a plurality of fins 38 extends andprotrudes from the base portion 36, as illustrated. Additionally, thefin frame 34 includes each of a plurality of openings 40 through the finframe 34. In various implementations, each fin 34 may be partially“punched” out from the base portion 36, and bent upward, as previouslydescribed in this document, so as to protrude away from the base portion36.

In various implementations, an outline of the plurality of fins 38 maybe cut from a single sheet of material, and the fins 38 may be bentupward, as previously disclosed. The sheet of material may a singlepiece, or may be formed from multiple layers as previously described. Invarious other implementations, the plurality of fins 38 may be formedfrom a single sheet of material that is pressed into a die, thuspuncturing the sheet of material and simultaneously forming each of theplurality of fins 38. The fins and/or fin frame may be formed andprocessed with coatings or other materials using any method disclosed inthis document. Also, the fin frame may be coupled to the base portionusing any of the systems or structures previously described.

As illustrated in FIGS. 12 and 14, a shape of each opening of theplurality of openings 40 corresponds with a shape formed by two or morefins of the plurality of fins 38, as illustrated. As illustrated, theplurality of fins 38 are formed as pairs of fins, each of the pairs offins including complementarily angled portions 30 defined by a diagonalline (or N-shaped line) between each fin in each pair of fins. In suchimplementations, each fin in each pair of fins may be substantiallytrapezoidal in shape and each fin substantially a mirror image of theother fin. As illustrated, each pair of fins are located on an opposingedge of each opening of the plurality of openings 40.

Referring to FIG. 13, a top view of the fin frame assembly of FIG. 12 isillustrated. The fin frame 34 includes the plurality of fins 38, orprojections, that are bent upward, and protrude away at an angle fromthe base portion 36 of the fin frame 34, as illustrated. In variousimplementations, by non-limiting example, each fin 38 may extend orprotrude at a 45 degree angle relative to the base portion 36, or eachfin 38 may extend or protrude at more or less than 45 degrees to thebase portion 36, so as to allow the flow of fluid over the fins 38. Inother various implementations, by non-limiting example, each pair offins 38 extend or protrude at opposing angles relative to each other andthe base portion 36. As illustrated, voids created by the folded andprotruding fins 38 creates openings 40 that correspond with the shape ofeach pair of fins. As illustrated, the fins 38 are uniform in size andshape, relative to each pair of fins, and are arranged in staggered rowsacross the base portion 36. In other various implementations, bynon-limiting example, the fins 38 may be arranged in any other desiredpattern on the base portion 36.

Referring to FIG. 14, a magnified view of the fin frame assembly of FIG.12 is illustrated. As illustrated, each fin of each pair of fins in theplurality of fins 38 includes a complimentary angled portion 30 betweeneach substantially trapezoidal shaped fin, and thus the opening 40created in the base portion 36 by each pair of fins is substantiallyrectangular in shape.

Referring to FIG. 15, a lengthwise side view of the implementation ofthe fin frame assembly of FIG. 12 is illustrated. The base portion 36 ofthe fin frame is coupled with the baseplate 32, as illustrated. Theplurality of fins 38 extend, protrude, or project outwards from thebaseplate 32 and base portion 36, as illustrated forming rows ofoppositely oriented angled features. Referring now to FIG. 16, awidthwise side view of the implementation of the fin frame assembly ofFIG. 12 is illustrated. In this orientation, the fins form triangularlyarranged rows of angled fins in the direction of fluid flow, which aredesigned to cause low pressure drop across the fin frame assembly.

Referring to FIG. 17, another implementation of a fin frame assemblyincluding a baseplate is illustrated. The baseplate 42 may be anydisclosed in this document. As illustrated, the fin frame assembly alsoincludes a plurality of strips of material 47 that are bent, stamped,folded, or the like, into repeating shapes along the length of the stripof material, as illustrated. As illustrated, a first set of projections48 and base portions 46 are formed in the strip of material 47. Asshown, each strip of material 47 also includes a plurality of baseportions 46 that are configured to couple to the baseplate 42. Invarious implementations, the base portions 46 are substantially planar,and are designed to couple to a substantially planar baseplate 42,though the base portions 46 can be configured to couple to a baseplatewith a non-planar/textured surface as well. In various implementations,the projections 48 are regularly spaced apart from one another like thatillustrated in FIG. 17, though in other implementations, the projections48 may be irregularly spaced along the strip of material 47. Asillustrated, a second set of projections 50 and base portions 46 areformed from another strip of material 49. The second set of projections50 and base portions 46 may be formed into the same shapes as the firstset of projections 48 and base portions 46 or into a different shapesfrom the first set of projections and/or base portions 46. Asillustrated, the shapes of the each of the projections 48, 50 maysubstantially form an isosceles trapezoid. As illustrated, the first setof projections 48 is staggered relative to the second set of projections50 through the projections formed in the first strip of material 47being formed in a different order along the strip than in the secondstrip of material 49. In other various implementations, there may bethree or more sets of projections that are staggered relative to eachother arranged and ordered side by side in various combinations. In thisway, desired fluid or air pathways can be created.

Still referring to FIG. 17, each of the projections 48, 50 extends andprotrudes away from the base portions 46 and baseplate 42, asillustrated. In various implementations, the projections 48, 50 may betreated to further enhance their thermal conductivity, such as bycoating or otherwise processing the projections 48, 50 using any methodor structure like that disclosed for the various fin implementations. Insuch implementations, such a coating or treatment can be applied to theentire fin frame assembly. In various implementations, by non-limitingexample, the strips of material 47, 49 may be bonded to the baseplate 42by one of welding, glue, epoxy, soldering, or any other coupling methoddisclosed herein. In other various implementations, the strips ofmaterial 47, 49 may be coupled together in various sets of strips, ormay be coupled to a common base, which may then be coupled to thebaseplate 42. In various implementations, the strips of material 47, 49may be made of a single piece of material or may be made of two or morelayers of material like any fin implementation disclosed herein. The finframe assembly can then be used with a baseplate and fluid heat transferjacket like any disclosed herein.

Referring to FIG. 18, a top view of the fin frame assembly of FIG. 17 isillustrated. As illustrated, the projections 48, 50 are uniform in sizeand shape, and are staggered in rows across the baseplate. Thisarrangement formed by putting the different strips in a desired order tocreate the staggering may be formed to improve the heat transferavailable from of the projections 48, 50 to the fluid. In other variousimplementations, by non-limiting example, the projections 48, 50 may bearranged in any other pattern or may be randomly arranged relative toone another.

Referring to FIG. 19, a magnified view of the fin frame assembly of FIG.17 is illustrated. As illustrated, each projection 48, 50 protrudes awayfrom its corresponding base portion 46, by folding/bending the materialof the strip. In the implementation illustrated, the shape of eachprojection may form an isosceles trapezoid. However in otherimplementations, the projections 48, 50 may be of different shapes,sizes, may be angled, and may have different orientations relative toone another.

Referring to FIG. 20, a lengthwise side view of the implementation ofthe fin frame assembly of FIG. 17 is illustrated. In thisimplementation, similar to the fin versions previously illustrated, theprojections place most of the material in the array parallel with thedirection of flow of the fluid. Referring now to FIG. 21, a widthwiseside view of the implementation of the fin frame assembly of FIG. 20 isillustrated. As illustrated, in this view, the projections form a set ofchannels along the fin frame which may assist in facilitating heattransfer through creating turbulent flow or more laminar flowconditions, depending on what is desired.

Referring to FIG. 22, a magnified perspective view of the implementationof another fin frame assembly including higher and lower projections isillustrated. The strips of material 54, 56 are coupled to the baseplate58, as illustrated. In various implementations, the size and shape ofeach base portion 60 may be the same or similar, as illustrated. Asillustrated, a first group 53 of the first set of projections 62 isregularly higher than a second group 51 of the first set of projections62. In various implementations, a first group of the second set ofprojections 64 may also be higher than a second group of the second setof projections 64. In various implementations, there may be three, four,or more different heights of raised portions of the projections. Invarious implementations, there may be a raised portion that has twoheights, resulting in a stepped profile of projections. In variousimplementations, the second group 51 of the first set of projections 62may have a peaked top while the first group 53 may have a flat top, asillustrated. In various other implementations, the profile of the top ofthe projections 62, 64 can be of any suitable combination of peaked andflat tops, including all peaked, all flat, and some of each. The lengthof the flat top can vary as well, with some being greater in length thanothers. As illustrated, the strips of material 54, 56 can be arranged ina staggered pattern with the second group 51 of the first set ofprojections 62 of a first strip of material 54 being aligned with afirst (higher) group of the second set of projections 64 of the secondstrip of material 56. Fluid, or air, is then allowed to flow, or isurged to flow, through the strips and underneath the projections toadvantageously conduct thermal energy away from the baseplate 58.

Referring to FIG. 23, a magnified perspective view of the implementationof the fin frame assembly of FIG. 17 including recesses is illustrated.As illustrated, the baseplate 58 can include a pattern of recesses 52 onits surface that correspond to receive the perimeters of the baseportions 60 of the strips of material 54, 56. In variousimplementations, the pattern of the recesses 52 may be configuredaccording to the staggered pattern of the strips of material 54, 56and/or to the pattern of the projections 62, 64. In variousimplementations, the recesses 52 can be slightly larger in size than theperimeters of the base portions 60 so that there is not a friction fitbetween the baseplate 58 and the base portion 60; rather the recess 52serves as a locating/bonding feature for attachment. In variousimplementations, the recesses 52 can help to apply an adhesive, epoxy,or other bonding material, or to serve as a locator for a welding orsoldering operation. In such implementations, an adhesive or bondingmaterial can be placed onto the entire surface of the baseplate 42 andthen excess adhesive or bonding material can be wiped from the surfaceof the baseplate 58 with a flat scraper, leaving adhesive in therecesses 52 and not on the remaining surface of the baseplate 58. Inthis way, the adhesive or bonding can be used to couple the baseportions 60 into the recesses.

In other implementations, the recesses may not be used and the variousstrips of material may be bonded/coupled to the baseplate using any ofthe methods disclosed in this document.

In places where the description above refers to particularimplementations of fin frame assemblies and implementing components,sub-components, methods and sub-methods, it should be readily apparentthat a number of modifications may be made without departing from thespirit thereof and that these implementations, implementing components,sub-components, methods and sub-methods may be applied to other finframe assemblies.
